In my journey to branch out from web development, I’ve been exploring both game design, animation, and CNC programming. Naturally, I’ve stumbled upon the concept of a PID Controller as I was trying to understand how to implement a “natural” look of feedback in an animated vehicle.

For this demo, I’ve constructed a basic webgl space with a “train” (or car, if my models load correctly…) that attempts to reach a spot on the track. During the loop, you can click on other parts of the track and change the PID parameters to get a sense of how those inputs impact the feedback loop.
